Model is slightly better/cheaper to the BW-C3 version already posted.
Apparently (edit):
BW-C9 is QC3.0 (on the USB-A port), whereas BW-C3 (the other deal) is Power3S (doesn't have QC).
Doesn't look like it's particularly different apart from the "NT6008 Fast Charge Chip" and the port being orange coloured on the C9, which as we all know speeds up charging (though not as much as red fire decals).
Qualcomm Quick Charge 3.0 Tech :
Qualcomm Quick Charge 3.0 is engineered to refuel devices up to four times faster than conventional charging.
It is designed to charge twice as fast as Quick Charge 1.0 and to be 38% more efficient than Quick Charge 2.0.
With Quick Charge 3.0 you can charge a typical phone from 0 to 80% in about 35 minutes.BlitzWolf BW-C9 Car Charger's NT6008 Fast Charge Chip:
